BAKING PAN.

This invention relates to containers formed from sheet metal and frequently from tin plate. Containers of this kind are widely usedin the baking industry, particularly b 5 wholesale bakeries for the making of brea cake and similararticles.

The object of this invention is toprovide a simple, efficient, economical equipment with certain mechanical advantages both in no handling and using'wblich will be later set" forth.

- Referring to the drawing:

Fig. I shows a erspective view'of a 'set of pans united toget er in a manner typical of Fig. II shows a detail of the corner portion of one of the end pans of the set shown in Fig. I;

ig. III shows another detail partly in sec-- tionof the corner of one pan of the setshown in Fig. I and a corresponding portion of a second pannested within the 'first pan the condition disclosed being further representative of what will occurv when two or more individual sets of pans, as shown in Fig. I

are nested together;

Fig. IV shows a corner detail of the end pan of Fig. I modified slightly from the construction shown inFig. II;

Fig. V shows a detail artly in section of the end palrindicated in liig. IV with a secondpan nested within the first pan and in-. dicates the general condition which will obtainif two sets of pans made in-accordance with the details given in Figures IV. and V are nested together.

It will be understood that my invention may be applied to one pan or a set of pans,

but under present commercial conditions o pans of the type commonly used are manu- Iactured most often in groups or sets 0t any number ranging from two to in some-cases six or.'eight. It will be understood that the number of pans in the set has no bearing on my invention. a

The pans may be constructed individually in a eat many ways, the drawings merely showing. one preferred form.

Referring to the drawings:

(1), (2) and (3) represent a set of three pans unitedtogether in accordance .with the usual practice in the construction'of this class of container. The individual pans may be constructed substantially identical, each Y with the other before being assembled intocontact with the pan, thus m 1927. Serial 'No. 196,612.

the set. The end pans of the set, however,

are provided. with a protection plate (4') extending for a considerable distance along the outer edge of the end pan (1). The protection plate maybe riveted, spot. welded or otherwise attached to-the outside wall of the an. (5) indicates a rivet-for holding the protection plate tothe pan'near its lower'portion. The upper side of said protection plate (,4) may be astened to the pan in'any desired way. I have indicated'that the upper edge (6) is pressed under strap (7) which extends along the sides of the series of pans" serving to reinforce them and'unite them to-. gether. The wall of the pan indicated by (8) is bent out-'Ward'and downward asv shown at 9 so as to-surround and hold in place strap 7 Many other methods may be employed for constructing these pans and I do not'wish to be confined to the exact details here disclosed as they merely. represent one commer cial and satisfactorymanner ofaccomplish= ing the desired end. The pans are shown as if drawn from a single sheet of nietal which is a.preferredconstruction, but not essential as, the pans may be folded or shaped 'by any desired process. Protection to have a projection (10) extending in a horizontal direction. The projection (10) is shown in Figures II and III as being near the upper portion of the protection-plate and slightly below strap member (7 I wish to polnt out, however, that the projection (10):

' may be located at any desired point or may be of any desired contour or sha The plate (4)ris drawn orformed on all, sides and in close a rejection closed aking a ti 'ht joint with the sides oft-he pan. Such a or.-

mation'serves to prevent the entrance of dough, grease or other materials into the space formed between the projection (10.) andthe wall of the pan. This 1s, of course, highly desirable as materials entering this space will tend to decay resulting in an unsanitary condition. I

' Projection ,member 10) extends outward away from the side of t e pan asufiicient distance, so that when the pan is placedwithi'n another pan in the condition which is described as nesting the projection (10) will servp to limit the amount that the inner pan will enter the outer pan. It W1ll be noted,

i creases the time required for cooling. It is,

tion.

therefore, desirable to maintain a certain definite spacing between adjacent pans when nested as will be subsequently set forth.

- Referring to Fig. III (11) indicated a projection on a second an (12) which is nested into pan (1). (13) indicates the edge of pan (12) which contains strap member (14) of pan (12). It will be apparent from Fig. III that projection (11) serves to limit the distance which pan (12) enters pan (1) and,

' therefore, accomplishes the result previously described.

In Fig. IV 15) indicates a pan which may be considered the endpan of a set being analogous, therefore, to pan (1) as previously described.

- Pan (15) is provided with a protection plate (16) which is attached to pan 15) in any desired manner. I have shown protection plate (16) riveted to pan 15) by rivet (17 although obviously spot welding or other expedients may be employed if desired.

' I Pan (15) has a side wall (18) which extendsoutwardly and downwardly as indicated by 19) and surrounds a strapping member 20 Protection plate (16,) at its upper'portion (21) is shown extending between strap member (20) and pan wall (18) this construction serving in conjunction with rivet (17) tolocate and hold plate (16) in posi l (22) indicates a second pan similar to (15 but nested within (15).-- (23) indicates the protection plate on pan (22) while (24) indicat-es-the strap member surrounded by-edge (25) of pan-(22). Protection plate (16) is provided with a-ridge or extension portion (26) which may be bent or drawn'or formedasdesired.-v (27) indicates a corresponding projecting ortion 'of.protecting plate (23) on pan (22 It will be apparent that the lower portion (28) of extension projection (27) restsfon the upper portion of the upper edge of pan 15) just above strap member (20 thus serving to control the distance that ('22 will enter into panc( 15) when the 're-.

. spective setsof pans are nested.

) what I claim as new and wish Itwill be noted that the contacting portion of the projecting member with the top of the pan below, is substantially horizontal at the point of contact. This is, shown clearly in Figure III and Figure V. Thus in Figure III the lowerportions of projection (11) at point of contact with edge of pan near point (9) is substantially horizontal. In the same way the contacting portion of expansion (27 where it meets top ends of lower pan (28) is substantially horizontal. The object of this construction is of course to prevent wedgingwhich would make the pans stick together, particularly on cooling and also more difficult to separate.

It will be apparent that one of the essential features of this invention is to produce in a practical commercial way some form of projection or stop such as is indicated by numbers (26) and (27) such stops being arranged tocome into contact with some predetern'lined portion of the next adjacent'set of pans when the two sets of pans are nested together.

It will be apparent from the above description that I have provided means for separating sets of pans when nested so that they will not become wedged or forced together due to their own weight or the method of handling. This is of great importance in the case of certain set of pans in that if pans become tightly wedged together they are slow to cool, hard tohandle and separate, and also likely to be dented or deformed. It will be understood that many possible variations of my device can be made and still come within the scope of this invention. Thus the actual shape, size, thickness or composition of the material is not essential. It is, of course, desirable to make a strong rugged structure which will stand the strains an d abuse of commercial handling.

Having nowfully described my invention to secure by Letters Patent in the United States is as follows:

1. In a set of baking pans a side plate 10- catcd adjacent to the outer wall of the outer pans of said set, said sideplate carrying a substantially flat horizontally extending supporting projection, reaching beyond the, upper edge of said an.

2. In a set of ba ring pans a substantially flat horizontally extending supporting projection on the outer wall of a pan. saidsupporting portion projection extending horizontally beyond the upper edge of said pan.
